State police said a seventh-grade student opened fire Tuesday in the Berrendo Middle School gym, injuring two of his classmates.

Roswell Independent Schools Superintendent Tom Burris said the staff and students performed very well when the real thing happened because they've been through active shooter drills before.

"In the 10 seconds that transpired from the time of this thing starting until the teacher had control of the weapon, there was no cowardice. It was protection for our kids," Burris said.Burris said his heart went out to both the children who were hurt and those who saw the incident happen.
